Earthquakes and Emergence

Here are a few maps showing the boundaries of tectonic plates, specifically those around the Pacific Ring of Fire, helpfully traced out by 100+ years of earthquakes. I think about emergence sort of a lot, and this is convenient, because map making with big-ish data often results in blowing the dust off a larger-order system. You can explore this in more detail via this story map.
